Zvichienderana nechimiro nehurefu, fiber yegirazi inogona kukamurwa kuita fiber inoenderera mberi, fiber yakareba zvakatarwa uye girazi wool; zvichienderana nekugadzirwa kwegirazi, inogona kukamurwa kuita fiberglass isina alkali, resistance yemakemikari, medium alkali, high strength, high elastic modulus uye alkali resistance (alkali resistance), nezvimwewo.
Zvinhu zvikuru zvekugadzira fiber yegirazi ndeizvi: jecha re quartz, alumina uye pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite, nezvimwewo. Nzira dzekugadzira dzakakamurwa kuita zvikamu zviviri: chimwe ndechekugadzira girazi rakanyungudutswa kuita fibers; chimwe ndechekutanga kugadzira girazi rakanyungudutswa kuita mabhora egirazi kana tsvimbo dzine dhayamita ye 20 mm, uye wozopisa nekunyungudutsa nenzira dzakasiyana-siyana kugadzira mabhora egirazi kana tsvimbo dzine dhayamita ye 3 kusvika 3 mm. 80μm fibers dzakapfava kwazvo. Fibers dzakareba dzisingaperi dzinodhonzwa nenzira yekudhirowa kwemechanical yeplatinum alloy plates dzinonzi continuous glass fibers, dzinozivikanwa se long fibers. Discontinuous fibers dzinogadzirwa nema rollers kana air flow, dzinonzi fixed-length glass fibers, dzinozivikanwa se short fibers.
Mashinda egirazi anopatsanurwa muzvikamu zvakasiyana zvichienderana nekuumbwa kwawo, hunhu uye mashandisirwo awo. Zvichienderana nemitemo yegiredhi yakajairika, fiber yegirazi yeE-grade inoshandiswa zvakanyanya uye inoshandiswa zvakanyanya muzvinhu zvinodzivirira magetsi; S-grade ifiber yakakosha.
Girazi rinoshandiswa mukugadzira fiberglass rakasiyana negirazi rinoshandiswa mune zvimwe zvigadzirwa zvegirazi. Kazhinji, magadzirirwo egirazi emafiber akambotengeswa ndeaya anotevera:
Fiberglass ine simba guru uye modulus yakakwira
Inoratidzwa nekusimba kwayo kukuru uye modulus yakakwira. Simba rayo rekudhonza fiber imwe chete i2800MPa, inova yakakwira ne25% kupfuura yefiber yegirazi isina alkali, uye modulus yayo inochinjika i86000MPa, inova yakakwira kupfuura fiber yeE-glass. Zvigadzirwa zveFRP zvinogadzirwa nazvo zvinonyanya kushandiswa muindasitiri yemauto, mundege, njanji dzinomhanya zvakanyanya, simba remhepo, zvombo zvinodzivirira mabara uye midziyo yemitambo.
Firiji yeAR
Inozivikanwawo sefayibha yegirazi inodzivirira alkali, fayibha yegirazi inodzivirira alkali chinhu chinosimbisa kongiri yegirazi yakasimbiswa (simende) (inonzi GRC), fayibha isingasanganisike yemhando yepamusoro, uye inotsiva simbi neasbestos muzvinhu zvesimende zvisingatakure mutoro. Hunhu hwefayibha yegirazi inodzivirira alkali hwakanaka, inogona kudzivirira kuputsika kwezvinhu zvine alkali yakawanda musimende, simba rakasimba rekubata, modulus yakakwira, kuramba kukanganiswa, simba rekukwenya nekukotama, isingatsve, inodzivirira chando, inodzivirira tembiricha, kugona kushandura hunyoro hwakasimba, kuramba kupwanyika nekusapinda zvakanaka, dhizaini yakasimba, kuumbwa nyore, nezvimwewo, fayibha yegirazi inodzivirira alkali rudzi rutsva rwekusimbisa kwegirini uye kune nharaunda kunoshandiswa zvakanyanya mukongiri yakasimbiswa (simende) yepamusoro.
Girazi reD
Inozivikanwawo segirazi rine dielectric shoma, inoshandiswa kugadzira magirazi ane dielectric shoma ane simba rakanaka re dielectric.
Pamusoro pezvinhu zvegirazi zvataurwa pamusoro apa, faibha itsva yegirazi isina alkali yava kuwanikwa, isina boron zvachose, zvichideredza kusvibiswa kwezvakatipoteredza, asi hunhu hwayo hwemagetsi hwekudzivirira kupisa uye hunhu hwemakanika hwakafanana negirazi rekare reE. Pamusoro pezvo, kune faibha yegirazi ine magirazi maviri, iyo yakashandiswa mukugadzira girazi remvere, uye inonziwo ine mukana wekusimbisa fiberglass. Pamusoro pezvo, kune faibha yegirazi isina fluorine, inova faibha yegirazi isina alkali yakagadziriswa kuti ichengetedze nharaunda.

Unogona kupatsanura fiberglass muzvikamu zvakasiyana, zvichienderana nezvinhu zvakashandiswa uye huwandu hwazvo.
Heano marudzi manomwe akasiyana e fiberglass uye mashandisirwo awo muzvigadzirwa zvezuva nezuva:
Girazi reAlkali (A-girazi)
Girazi resoda kana kuti girazi resoda lime. Ndiro rinonyanya kushandiswa nefiberglass. Girazi realkali rinoita 90% yegirazi rese rinogadzirwa. Ndiro rinonyanya kushandiswa uye rinoshandiswa kugadzira magirazi, akadai semagaba nemabhodhoro ezvekudya nezvinwiwa, uye magirazi epahwindo.
Midziyo yekubikira yakagadzirwa negirazi re lime re soda rakanyorova muenzaniso wakanaka wegirazi re A. Rinodhura zvishoma, rinogoneka, uye rakaoma. Magirazi emhando ye A anogona kunyungudutswa uye kunyoroveswa kakawanda uye ndiwo marudzi egirazi akakodzera ekudzokorodza magirazi.
Girazi rinodzivirira alkali reAE-girazi kana AR-girazi
Girazi reAE kana AR rinomiririra girazi rinodzivirira alkali, iro rinoshandiswa zvakanyanya kugadzira kongiri. Ichinhu chakasanganiswa chakagadzirwa ne zirconia.
Kuwedzerwa kwe zirconia, chicherwa chakaoma, chisingapise kupisa, kunoita kuti fiberglass iyi ikodzere kushandiswa mu simende. Girazi reAR rinodzivirira simende kutsemuka nekupa simba uye kuchinjika. Uyewo, kusiyana nesimbi, harina ngura nyore nyore.
Girazi remakemikari
Girazi reC-girazi kana girazi remakemikari rinoshandiswa sechinongedzo chepamusoro chejira rekunze rema laminates emapombi nemidziyo yekuchengetera mvura nemakemikari. Nekuda kwekuwanda kwecalcium borosilicate inoshandiswa mukugadzira girazi, rinoratidza kusakwanisa makemikari zvakanyanya munzvimbo dzinopisa.
Girazi reC rinochengetedza kuenzana kwemakemikari nechimiro munzvimbo chero ipi zvayo uye rinodzivirira makemikari ane alkaline.
Girazi reDielectric
Magirazi eDielectric (D-glass) fibers anowanzo shandiswa mumidziyo yemagetsi, mumidziyo yekubikira, nezvimwewo. Imhando yakanaka yefiberglass nekuda kwekusagadzikana kwayo kwe dielectric. Izvi zvinokonzerwa nekuvapo kwe boron trioxide mukugadzirwa kwayo.
Girazi remagetsi
Machira e-girazi kana kuti E-fiberglass ndiwo mwero weindasitiri unopa chiyero pakati pekushanda nemutengo. Chinhu chakareruka chakabatanidzwa chinoshandiswa mundege, mugungwa uye munzvimbo dzemaindasitiri. Hunhu hwe-girazi sefiber inosimbisa hunoita kuti ive chinhu chinofarirwa nezvigadzirwa zvekutengesa zvakaita semapuranga, mapuranga ekusefa, uye magwa.
Girazi remagetsi rinogadzirwa neshinda dzemagirazi rinogona kugadzirwa chero chimiro kana saizi uchishandisa nzira iri nyore yekugadzira. Pakugadzirwa kweshinda dzemagetsi, hunhu hweshinda dzemagetsi dzinoita kuti dzive dzakachena uye dzakachengeteka kushanda nadzo.
Girazi remukati
Girazi rechimiro (S glass) rinozivikanwa nehunyanzvi hwaro hwemakanika. Mazita ekutengeserana ekuti R-glass, S-glass uye T-glass ese anoreva mhando imwe chete yefiberglass. Kana ichienzaniswa neE-glass fiber, ine simba rakawanda rekudhonza uye modulus. Iyi fiberglass yakagadzirirwa kushandiswa muindasitiri dzekudzivirira nedzemuchadenga.
Inoshandiswawo muzvishandiso zvekudzivirira simbi zvakasimba. Nekuti rudzi urwu rwegirazi fiber runoshanda zvakanyanya, runoshandiswa chete mumaindasitiri chaiwo ane huwandu hushoma hwekugadzira. Izvi zvinorevawo kuti S-glass inogona kudhura.
Advantex fiberglass
Rudzi urwu rwefiberglass runoshandiswa zvakanyanya mumaindasitiri emafuta, gasi uye migodhi, pamwe chete nemafekitori emagetsi uye mashandisirwo emugungwa (masisitimu ekuchenesa tsvina nemvura yakasviba). Inobatanidza hunhu hwemagetsi nemagetsi eE-glass neresistance yeacid corrosion yeE, C, naR glass fibers. Inoshandiswa munzvimbo dzine zvivakwa zviri nyore kubatwa nengura.
